3 + 6 - 2 + 14 - 3 + 2 = 20

15/20 minus 6/20 which is 9/20 or 0.45

20

3/5 - 3/4 = 12/20 - 15/20 = (12 - 15)/20 = -3/20

13/20 - 3/15 = 9/20

x - 3

x - 5

6 days 15 hours minus 3 days 20 hours equal 2 days 19 hours.

15 + 3 - (6 x 4) = -6

32 - (15 x 2) + 3 = 5

12-3(2+15) = -39

y equals 3

your answer would be 20

It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3

if 'g' = minus 3 then 20 + -3 = 17 17 + -3 = 14

Converting to twentieths, we get 8 over 20 minus 15 over 20, resulting in minus 7 over 20.

It is: 5/12 minus 3/20 = 4/15

24/20 - 15/20 = 9/20

3/4 - 1/10 = 15/20 - 2/20 = 13/20

Plus/minus 3 to plus/minus 15, with a maximum open circuit range of plus/minus 25. For a status line, such as DTE or CTS, plus is true, minus is false. For a data line, such as TXD or RXD, minus is marking or 1, plus is spacing or 0. (Note the inversion at the UART.)

3x^2=-20 so x^2=-20/3 this has no real roots but the plus of minus i(square root of 20/3) is a solution if we allow complex numbers.

Zero

3/4 - 2/5 = 15/20 - 8/20 = 7/20

(x - 5)(x - 3)
